Remote inspection, measurement and handling techniques are under development for use in CERN's particle accelerator facilities to reduce radiation exposure of personnel and reduce facility downtime when scheduled maintenance or breakdown repairs are needed. This paper gives an explanation of the potential benefits to CERN of remote inspection, measurement and handling along with a brief history of remote handling work at CERN. Recent projects are then described, covering the development work and operations forming part of CERN's recent remote inspection, measurement and handling activities.

Intervention planning is crucial for maintenance operations in particle accelerator environments with ionizing radiation, during which the radiation dose received by maintenance workers should be reduced to a minimum. In this context, we discuss the development of a new software tool and the entailed methodology, including the visualization aspects. The software tool integrates interactive exploration of a scene depicting an accelerator facility augmented with residual radiation level simulations, with the visualization of intervention data such as the followed trajectory and maintenance tasks. Its conception allows for future inclusion of measurements performed by mobile robotic devices. In this work, we explore the systems engineering life cycle of the development process of an interactive intervention planner, which includes the needs analysis, specification explicitation, conceptual mathematical modelling, iterative implementation, design and prototype testing and usability testing.
